Esteemed hackers,
I can't be the only person to have encountered a situation where
adding a new foreign key pointing at a busy table essentially never
happens because the way things work now, creating the constraint
trigger on that busy table requires an AccessExclusive lock, or a
unicorn,

2) Is there another way to solve the problem of adding a foreign
key constraint that points at a busy table?
Add it as NOT VALID and do a later VALIDATE CONSTRAINT step, after the
patch to reduce lock levels for ALTER TABLE goes in, perhaps?
